The scsi headers are exported. So it does not matter if glibc or any
other libc for that amtter uses the headers or not.
Exported headers has some rules to follow and scsi are no exception here.

Now if we get the scsi headers in good shape then and only then we can 
go to glibc people and tell them that we have a better set of scsi headers
than they have.

Postponing updates to the exported scsi headers just beacause we do not
have any users of them at the moment is the wrong thing to do.
We should rather use the opportunity to streamline the exported headers
so we have a superior set of headers to offer.
